Hi, All Why would a eCPM go up a certain amount and then go down again on the same day?
Thank you for getting back to me. I also have a Childrens book on Amazon. I need to give you a Rumble if I can figure it outIt’s all estimations and changes as the actual numbers come in. Theoretically it’s more accurate as time goes on but you never know anything for certain until the funds go into your account.
